Hello,

I got this error trying to use your Omnigen node after installation.

Thank you in advance for your help.

It looks like you're encountering an import error due to a missing or incompatible component, specifically PeftAdapterMixin from diffusers.loaders. This could be due to either an outdated or incompatible version of the diffusers library.
Update the diffusers library: Make sure you're using the latest version of diffusers by running:
pip install --upgrade diffusers

i was have the same issue, after update the diffusers, the error gone.
